Non-Sense Why BackRoll? When Do I Need To BACK ROLL? How to Paint Like a PRO!

What happens here

This step focuses on smooth, non-porous surfaces like a metal door. The host explains that if such a surface, which likely has a smooth factory finish and is already primed, is sprayed with an airless sprayer, it will achieve a glass-like, automotive-quality finish. Back rolling or back brushing this type of surface would introduce brush strokes or stippling (texture from the roller), ruining the desired smooth finish and not providing any benefit in terms of adhesion or penetration, as the surface is not porous and already has good adhesion.

Goal: Determine when NOT to back roll or back brush to preserve a smooth finish.

Tools and materials

  • Airless Sprayer — Applying paint to the metal door
  • Metal Door — Example of a smooth, non-porous surface
  • Paint — The coating for the door

Academy right here I have a metal door right over there and we'll talk about the metal door right now so if I spray that metal door we'll give you a close-up look at that door that's a metal door it's got a smooth finish there's no wood graining to it or anything it's a smooth finish if I spray it with an airless sprayer it's gonna have on this really nice glass like automobile like finish and it's gonna look amazing it's not porous it's smooth and it doesn't need to have any hands that he's it's already painted and it's already been primed and painted we're gonna be painting right over the top of it if I do back roll it or back brush it will start off with back brushing it's gonna cause roping or brush strokes and it's just not gonna have that automobile like finish if I back roll it it's gonna stipple it and leave stippling all over that door and it's just not gonna look glossy like it was sprayed and that's one of the benefits to spray and it's getting that really really nice looking finish the trim around that door has been sprayed and the door itself has been sprayed so I definitely would not want to back roll
